This tutorial title is misleading- it is *NOT* testing a resistor "in-circuit". This video isn't even testing a resistor in a circuit, it is testing a resistor as a discreet component. You should change the title of this video to something like "how to measure a resistor's value".
Right. Apparently electronics have feelings now. If you "suspect" a component is bad just remove it and test it. If you hate a component because it hurts your feelings just remove it. Heck just remove 50 components and test them all for the sake of feelings.and now we can't dislike videos because of feelings. Every video now is 100% accurate information.
If I use a multimeter to test voltage across resistor in a circuit with supplied 12v and it reads , will the multimeter still reads the voltage across the resistor if I open the supply since the multimeter have a battery? Looking forward to your answer. Thanks
No, it is not necessary .... Please watch the video again "If you suspect that a resistor may be faulty this is method to check it " This is the content of the video If we suspect a resistance, by doing so we confirm whether it is faulty or not If a board has 100 resistors, you do not need to remove each one separately. Must also have basic electronic knowledge to suspect which resistor is faulty It also depends on experience So, watch the video again and improve your knowledge I am happy and appreciative of your comments Have a nice day thank you
@@EEEWORKSHOP So if there are 100 resistors, how does one with much skills as yourself determine which one looks suspicious? I usually call scooby and the gang to solve such mysteries, but I’m hoping you can give me a clue. 😎
@@globalmagicnation8464 In electronic circuits, resistors are mainly used to reduce current flow (i.e. resistors function is like a valve that controls the amount of water that passes through it). If a resistor is dead no current passes through it (like a dead fuse or a dead light bulb) and if a resistor is faulty it passes less or more current that it was supposed to pass. You can measure the performance of a resistor (and other electronic devices) on a live circuit board, but this needs knowledge and skills and tools. You can measure the amp that goes into the resistor and the amp that comes out of the resistor then decide if the resistor is doing its intended function or not
Sir There is a PCB Circuit, in such case If we try to Replace Components Such As Replace N-Channel MOSFET With IGBT while how can I calculate Resistor, capacitor Value it's series' and parallel ?
It should show an infinite value, usually shown as a value of 1. But try the different positions on your multimeter 20K, 2000K, 200, and the other ones, if they all show 1, you have a bad resistor.
